At some point, all mobile app users lose their data signal. Join us to learn best-practices for coding for offline requirements with the Salesforce Mobile SDK. We'll develop a simple app using SmartStore offline storage, highlighting the SmartSQL and SmartSync features. With these tools, you can take your mobile apps to the next level, developing native and hybrid applications on iOS and Android that have offline access to your data.

16. REST API Returns a JSON Response
/services/data/v29.0/query/?q=SELECT Id, Name FROM Contact

17. Soups and Stores

18. Some things you can do with your soup…
• Register a Soup with an IndexSpec
• Query a Soup using a QuerySpec
• Upsert Data to a Soup
• Delete Data from a Soup
• Remove a Soup

19. IndexSpec
• JSON Object
• Fields to index
• “string” or “integer”
• [
• {"path":"Id","type":"string"},
• {"path":"Name","type":"string"}
• ]

20. QuerySpec
buildAllQuerySpec(path,order,pageSize)
Query all records from the object in the given sort order (or null order)
buildExactQuerySpec(path,matchKey,pageSize)
Search for records with index path values matching the key.
buildRangeQuerySpec(path,beginKey,endKey,pageSize)
Return all records with an index path value between the two range values
buildLikeQuerySpec(path,likeKey,order,pageSize)
Basically “select * from [table] LIKE ‘%[likeKey]%’”
buildSmartQuerySpec(smartSql,pageSize)
Basically “select * from [table] LIKE ‘%[likeKey]%’”

21. SmartSQL
•SELECT {departments:name}, {employees:lastName}
•FROM {employees}, {departments}
•WHERE {departments:deptCode} = {employees:deptCode}
•ORDER by {departments:name}, {employees:lastName}

22. SmartSync

23. SmartSync
• Extends Backbone.js
• Can be used with or without a SmartStore Cache
• Queries returned as Backbone Model Collections

24. Backbone
• MV* Framework
• Models: Individual records
• Collections: Collections of Model records
• View: Javascript backing for the stuff that you see
• Router: routes everything after the # in a URL to application functions
• http://myapp.com/#/user/list

25. Force.SObject
• sobjectType: Account, Opportunity, etc.
• fieldlist: ["Id", "Name", "Amount", "StageName"]
• cacheMode: client, server write order
• mergeMode: how to handle conflicts
• cache: if using SmartStore
• cacheForOriginals: backup data for conflict detection

26. Force.SObjectCollection
• config: determines queries used to access data
• cache: if using SmartStore
• cacheForOriginals: backup data for conflict detection

27. Force.StoreCache
• soupName: Name of the SmartStore Soup
• additionalIndexSpecs: IndexSpecs to use, in addition to defaults
• keyField: Name of the field containing the record Id
• __locally_created__
• __locally_updated__
• __locally_deleted__
• __local__ (set to true if any of the previous three are true)
